Usage: nomad server force-leave [options] <node>
Forces an server to enter the "left" state. This can be used to
eject nodes which have failed and will not rejoin the cluster.
Note that if the member is actually still alive, it will
eventually rejoin the cluster again.
If ACLs are enabled, this option requires a token with the 'agent:write'
capability.
